Fortunately, the law is actually quite sane in this area, so there won't be any engineers going to prison for vehicular manslaughter: Manslaughter is the unlawful killing of a human being without malice. It is of three kinds: (c) Vehicular— (1) Except as provided in subdivision (a) of Section 191.5, driving a vehicle in the commission of an unlawful act, not amounting to a felony, and with gross negligence; or driving a vehicle in the commission of a lawful act which might produce death, in an unlawful manner, and with gross negligence. (2) Driving a vehicle in the commission of an unlawful act, not amounting to a felony, but without gross negligence; or driving a vehicle in the commission of a lawful act which might produce death, in an unlawful manner, but without gross negligence. (3) Driving a vehicle in connection with a violation of paragraph (3) of subdivision (a) of Section 550, where the vehicular collision or vehicular accident was knowingly caused for financial gain and proximately resulted in the death of any person. This paragraph does not prevent prosecution of a defendant for the crime of murder.
